- I Application filed April 30, 1910. Serial No. 53,564.

To all whom it may concern: a

' lie at knownthat T. ()LOF ANDERSON, a

citizen of the United States, residing at Chicago. in the county f (ooh and'Statejof Illinois, have invented a new and useful Im- Cars, of than I v I My object is to provide uncoupling leverineehauisni for, more especially,freightcars, whereby displacement of the lockingwhich the following is a specificapin, to unlock the coupler, may be efiected' by thei'operator with either his hand or foot from one side of the car and with little effort.

-In the accompanyingdrawing-Figure 1 is a broken top plan view 'of a car end-sill,

'25. fbufl'er-block 6 is a bracket 7 having a bearbutler-block and coupling-member with my improvements in place; Fig. 2, aview. of the same parts in front elevation; Fig. 3, a side elevation of-the same; and Fig. 4, an enlarged perspective view of a detail of the construction.

Secured against the face of the end-sill 5 of the car-frame, beyond one end of the ing-opening 8 through it and a reducedextension 9, at an angle to the main arm of the bracket. Also secured to the end-sill 5, in the position shown, is a stirrup-frame 10.

The numeral 11 designates an uncouplingrod passing through the stirrup 10 and bent at its outer end to. form the crankor handle 12. The inner end-portion of the rod 11 is bent, a's shown at 13, to extend laterally in a horizontal direction. The rod 11 passes loosely through the opening 8 in the bracket 7 and .is provided adjacent to said bracket with an ofi-set"lttermiuating in an eye, or socket-pieec, 15 and resting normally on the bracket-extension 9'.

The numeral 16 designates a bar having a hook-shaped end 17 engaging theeye of the locking-pin 18 of the coupling-member 1%). The bar asses over and in contact with the bent or s ort arm'13 of the rod or lever 11,'

" and passes loosely through the eye 15. The

turning of the handle 12 to the right in Fig.

3 produces axial movement 9f therod or lver 11 and causes it in turning, in the bearpL'oveIneut in l neoupliug Mechanism foring-opening 8, to lift the bar .16 bodily,

owing to the engagementwith said barof the short arm 13 and off-set 14. Raising of the bar, as described. lifts the locking-pin'and unlocks the coupling member; The turning of the handle 12, as described, would be perplacement is hard to overcome.

able fulcrum formed by the eye 15. ."lhe' -ofl'set 14 and arm 13 are comparatively short, while the crank or'handle 12 is c0mparatively long, so that in turning the latter the bar 16 an'd lockingin may be lifted with little effort, or on or considerable leverage, as is desirable in case the locking-pin is not easily displaced. Downward pressure upon l-thehandle 12 may be effected by the operator, for example, while standing-upon the sill-step 20, and the lifting of the locking-pin is rendered easy by the compound leverformed by the rod ll with its' 'fulcruni at 9, lifting at its short arm against the lever;l6 with its fulcrum at 15.' 'It'often' hap ens, in practice, that a couplerlockingpin as\to be displaced while the car is moving; and fre uently, from one cause or another, the resistance of the pin a ainst dis:

The compound lever-mechanism which my construction fprovides greatly facilitates displacement 0 a locking-pin while the car is moving, because the operator may not only stand upon the sill-step while performing the operation but may hear his wholeweight, if'necessary,'upon the handle l2, which, with the aid'of the compounded leverage, raises the looking-pin no matter how it may resist such movement, in practice, and without dapper of accident to the operator.
